This Perspective article explores the challenges associated with direct application of photobiomodulation (PBM) to gut and presents a novel hypothesis for indirect health modulation through oral microbiome alteration. Given difficulties in delivering PBM effectively deep gastrointestinal tissues, an alternative approach involves targeting microbiome, which has demonstrated relationship microbiome. Research indicates that applied cavity could selectively alter microbial composition. alteration may, via oral-gut axis, indirectly impact health. hypothesis, supported by preliminary studies, suggests offer promising non-invasive strategy managing gut-related disorders. Furthermore, there may be link between brain diseases. proximity brain, PBM-induced changes microbiota help prevent neurological However, further investigation is necessary comprehensively elucidate underlying mechanisms therapeutic implications this approach.

Rotavirus (RV) is a leading pathogen causing diarrhea in children. In this study, total of 51 fecal samples from children with RV enteritis, 29 post-treatment samples, and 38 age-matched healthy controls were collected. Microbial DNA was isolated the followed by high throughput Illumina sequencing targeting 16 S rRNA gene. Compared to group, RV-infected group exhibited reduced microbial diversity. Both groups shared Firmicutes as dominant phylum. Additionally, abundance Proteobacteria increased significantly group. At genus level, among top 50 most abundant genera, 34 showed significant differences, these differential genera correlating certain clinical indicators such dehydration levels C-reactive protein (CRP). Notably, there no differences microbiota before after treatment Only 8.82% (3/34) recovery trend towards state. This study enhances understanding how infection alters gut structure provides scientific basis for improving diagnosis strategies.

Most brain development occurs in the "first 1000 days", a critical period from conception to child's second birthday. Critical processes that occur during this time include synaptogenesis, myelination, neural pruning, and formation of functioning neuronal circuits. Perturbations first days likely contribute later-life neurodegenerative disease, including sporadic amyotrophic lateral sclerosis (ALS). Neurodevelopment is determined by many events, maturation colonization infant microbiome its metabolites, specifically neurotransmitters, immune modulators, vitamins, short-chain fatty acids. Successful gut-brain axis function depend on maternal factors (stress exposure toxins pregnancy), mode delivery, quality postnatal environment, diet after weaning breast milk, nutritional deficiencies. While neonatal highly plastic, it remains prone dysbiosis which, once established, may persist into adulthood, thereby inducing chronic inflammation abnormal excitatory/inhibitory balance, resulting excitation. Both are recognized as key pathophysiological ALS.

Antibiotic resistance is a global health crisis exacerbated by the misuse of antibiotics in healthcare, agriculture, and environment. In an intensive care unit (ICU), where high antibiotic usage, invasive procedures, immunocompromised patients converge, risks are amplified, leading to multidrug-resistant organisms (MDROs) poor patient outcomes. The human microbiome plays crucial role development dissemination genes (ARGs) through mechanisms like horizontal gene transfer, biofilm formation, quorum sensing. Disruptions balance, or dysbiosis, further exacerbate resistance, particularly high-risk ICU environments. This study explores interactions ICU, highlighting machine learning (ML) as transformative tool. Machine algorithms analyze high-dimensional data, predict patterns, identify novel therapeutic targets. By integrating genomic, microbiome, clinical these models support personalized treatment strategies enhance infection control measures. results demonstrate potential improve stewardship outcomes, emphasizing its utility ICU-specific interventions. conclusion, addressing requires multidisciplinary approach combining advanced computational methods, research, expertise.

Background Norovirus (NoV) is a leading cause of acute gastroenteritis in pediatric populations worldwide. However, the role gut microbiota NoV pathogenesis remains poorly understood. Methods We conducted longitudinal metagenomic analysis fecal samples from 12 NoV-infected children and 13 age-matched healthy controls Northeast China. Microbial composition functional pathways were assessed using high-throughput shotgun sequencing bioinformatic profiling. Results infection was associated with significant microbial dysbiosis, including increased alpha diversity distinct taxonomic shifts. Notably, Bacteroides uniformis , Veillonella spp., Carjivirus communis enriched infected individuals. Functional revealed upregulation metabolic involved carbohydrate lipid processing. These alterations persisted over time correlated disease severity. Conclusions Our findings reveal novel associations between particularly enrichment which may influence host-pathogen interactions via or immune mechanisms. The identified signatures offer potential biomarkers for diagnosis targets microbiota-based therapeutic strategies infection.
